1972 K10/K20 SUBURBAN Lift questions

[Travisarmenta]

I'm throwing a set of 3/4 ton's under my K10 as well as a 6 inch Skyjacker lift

1: Will i need to do any drive-line modifications? I've heard that anything over a 4 inch lift will need some, but considering I'm putting a Dana 60 which has a longer housing and yoke(roughly 2 inches) longer than the GM 12 bolt i might be in the clear.

I'm also getting the runaround from vendors and skyjacker itself as far as kits go.

I plan on using the C260AKSS kit, but no one can give me a solid answer as far as what I can or can't pick out , I already have a Steering arm, I want to purchase different shocks, skyjacker tells me i cant get the kit without shocks, vendors just say they sell the leaf kit and nothing else, no extended brake lines or shocks.....

anybody have any luck purchasing a kit/ piecing together a kit that is budget friendly? say around $1000 give or take?

Thanks fellas.
